Preparing YourPlotter for Use
as a Digitizer
A plotter with an HP-IB interface must be set to an address less than
31 because the plotter cannot send the coordinates of a digitized point
to the computer when it is in listen—onlymode.
Use of a digitizing sight, available as an accessory with the 7470, is
recommended. The sight should be loaded manually into the pen holder
itself. It may be inserted into the pen holder from either side. Place the
flange on the digitizing sight on top of the arm of the pen holder. The
top of the sight will just clear the top of the pen holder. Push the sight
gently into the pen holder; it will snap into place.
CAUTION
The sight should not be stored in a pen stall; do not
store using front panel buttons or an SP command.
Remove the sight from the pen holder before raising the
PAPER LOADlever since the sight would be stored auto
matically when the lever is raised.
To remove the sight from the pen holder, pull either arm of the pen
holder forward and push the sight out of the pen holder.
The sight is used in the pen down position.
